Detailed implementation manners
[0055] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.
[0056] Based on the problems mentioned in the foregoing background technology, in the related art, the semi-active stabilizer bar system adjusts the hydraulic damping through an electromagnetic valve, but this method can only achieve the damping adjustment of the stabilizer bar, resulting in a monotonous function of the stabilizer bar.
[0057] To solve the above problems, the embodiments of the present application propose a stabilizer bar power generation system, control method, device, medium, product and vehicle. The stabilizer bar power generation system provided by the embodiments of the present application includes a stabilizer bar. When the stabilizer bar moves, it will drive the fluid to flow in the fluid pipeline; a fluid pipeline, on which an opening control valve is provided, and the opening control valve is used to adjust the flow of the fluid in the fluid pipeline; a power generation module, which is communicated with the fluid pipeline, and the power generation module generates electricity based on the flow of the fluid in the fluid pipeline. It can recover the energy of the stabilizer bar and realize the power generation function of the stabilizer bar.
[0058] Specifically, the stabilizer bar power generation system in the present application can be set on devices such as vehicles, and can be connected to the suspension of the vehicle to maintain the stability of the vehicle. Subsequently, taking the stabilizer bar power generation system installed on a vehicle as an example, each embodiment will be described in detail.
[0059] The present application provides a stabilizer bar power generation system 100. Please refer to Figure 1 , the stabilizer bar power generation system provided by the embodiments of the present application includes: A stabilizer bar 10, when the stabilizer bar 10 moves, it will drive the fluid to flow in the fluid pipeline; A fluid pipeline 20, on which an opening control valve 21 is provided, and the opening control valve 21 is used to adjust the flow of the fluid in the fluid pipeline 20; The power generation module 30 is in communication with the fluid pipeline 20 , and the power generation module 30 generates electricity based on the flow of the fluid in the fluid pipeline 20 .
[0060] In this embodiment, the stabilizer bar 10 can be connected to the suspension of the vehicle. When the vehicle turns, the vehicle body will roll due to the centrifugal force. For example, when the vehicle turns left, the right side of the vehicle body will lift up and the left side will tilt down. The stabilizer bar is connected to the suspension through the connecting rods at both ends. When the vehicle body rolls, the suspension on one side of the vehicle body will move upward, while the suspension on the other side will move downward. In this way, the movement of the stabilizer bar can reduce the roll of the vehicle body when turning, and improve the handling stability and ride comfort of the vehicle.
[0061] In this embodiment, the stabilizer bar power generation system 100 also includes a fluid pipeline 20. The structure between the fluid pipeline 20 and the stabilizer bar 10 can enable the stabilizer bar 10 and the fluid in the fluid pipeline 20 to be linked. When the stabilizer bar 10 moves, it will drive the fluid to flow in the fluid pipeline 20, thereby generating hydraulic energy to provide damping for the movement of the stabilizer bar 10.
[0062] In this embodiment, an opening regulating valve 21 is provided on the fluid pipeline 20. The opening of the opening regulating valve 21 can be adjusted by automatic, manual or other control operations. The opening regulating valve 21 can be a solenoid valve, such as a proportional solenoid valve, etc., and its opening can be changed by a control signal, so as to limit the flow in the fluid pipeline 20, change the hydraulic pressure, flow rate, etc. in the fluid pipeline 20, so that the damping of the stabilizer bar can be adjusted by the opening regulating valve 21, and the damping control of the stabilizer bar 10 is realized, so that the stabilizer bar 10 can better adapt to the driving environment of the vehicle and further improve the vehicle comfort.
[0063] In the present embodiment, the stabilizer bar power generation system 100 also includes a power generation module, a power generation module 30. The power generation module 30 is connected to the fluid pipeline 20. The flow of the fluid in the fluid pipeline 20 generates hydraulic energy, thereby driving the power generation module 30. The power generation module 30 generates electricity based on the flow of the fluid in the fluid pipeline 20 to recover the energy of the stabilizer bar 10 when it is active, thereby realizing the power generation function based on the drive of the stabilizer bar 10, and the opening regulating valve 21 set on the fluid pipeline 20 can adjust the flow of the fluid in the fluid pipeline 20, thereby adjusting the hydraulic energy that can be provided to the power generation module 30 to adjust the power generation power of the power generation module 30.
[0064] Since continuous fluid flow is required for power generation while damping adjustment needs to restrict the flow rate, it is generally difficult to coordinate the two. Therefore, damping control and power generation control are generally relatively separate, and the damping and power generation of the stabilizer bar are adjusted independently, resulting in response delay and energy loss. However, this problem is overcome by the embodiments of the present application. The system provided by the embodiments of the present application can coordinately achieve damping adjustment and power generation adjustment, reducing response delay and energy loss.
[0065] In one embodiment, the power generation module 30 includes a hydraulic motor 31 and a generator connected to the hydraulic motor 31; the hydraulic motor 31 is connected in series in the fluid pipeline 20 and drives the generator to generate electricity based on the flow of the fluid in the fluid pipeline 20.
[0066] In an embodiment, the power generation module 30 includes a hydraulic motor 31 and a generator (not shown in the figure) connected to the hydraulic motor 31. The hydraulic motor 31 is connected in series in the fluid pipeline 20, so that the power generation module 30 is in communication with the fluid pipeline 20. When the fluid in the fluid pipeline 20 flows through the hydraulic motor 31, the hydraulic motor 31 converts the hydraulic energy of the fluid flow into mechanical energy and drives the generator connected to the hydraulic motor 31 to generate electricity, recovering the energy of the fluid flow driven by the stabilizer bar 10 to achieve the power generation function.
[0067] In one embodiment, the stabilizer bar power generation system 100 further includes: A cylinder block 40 having a liquid cavity therein, a piston 41 is disposed in the liquid cavity, the fluid pipeline 20 is connected to the liquid cavity, the piston 41 is connected to the stabilizer bar 10, and when the stabilizer bar 10 moves, it will drive the piston 41 to move in the liquid cavity, so that the fluid flows in the liquid cavity and the fluid pipeline 20.
[0068] In this embodiment, the stabilizer bar power generation system 100 further includes a cylinder block 40. The cylinder block 40 is hollow inside, forming a cavity that can accommodate fluid, that is, the cylinder block 40 has a liquid cavity inside. The fluid can be an incompressible fluid, and common fluids on vehicles include oil, etc., which can better provide hydraulic pressure to achieve damping and power generation. The fluid pipeline 20 is connected to the liquid cavity, and a piston 41 is also disposed in the liquid cavity. The piston 41 is directly or indirectly connected to the stabilizer bar 10. In some embodiments, the stabilizer bar 10 can be the rigid double arms on both sides of the piston, or can be connected to the piston 41 through the rigid double arms on both sides of the piston, so that when the stabilizer bar 10 moves, it will drive the piston 41 to move in the liquid cavity. The movement of the piston 41 can drive the fluid in the liquid cavity to flow into the fluid pipeline 20, so that the fluid can flow in the liquid cavity and the fluid pipeline 20. Through such a simple power generation oil circuit structure, without an external power source, the movement of the stabilizer bar 10 drives the piston 41 to directly drive the fluid to flow and generate electricity, which can improve the power generation efficiency and reduce the system cost.
[0069] In one embodiment, the piston 41 divides the liquid chamber into a first chamber 42 and a second chamber 43. The first chamber 42 communicates with one end of the fluid pipeline 20, and the second chamber 43 communicates with the other end of the fluid pipeline 20.
[0070] In this embodiment, the piston 41 can divide the liquid chamber into the first chamber 42 and the second chamber 43. The fluid pipeline 20 has at least two ports. The first chamber 42 communicates with one end of the at least two ports of the fluid pipeline 20, and the second chamber 43 communicates with the other end of the at least two ports of the fluid pipeline 20, so that the first chamber 42 and the second chamber 43 respectively communicate with different ports of the fluid pipeline 20. In this way, a hydraulic circuit can be formed, and the piston 41 can move bidirectionally in the liquid chamber. Thus, when the stabilizer bar 10 drives the piston 41 to move arbitrarily, it can cause the fluid to flow in the liquid chamber and the fluid pipeline 20, thereby realizing damping in different directions and further improving the power generation efficiency.
[0071] In one embodiment, a first pressure sensor 44 is arranged in the first chamber 42, and a second pressure sensor 45 is arranged in the second chamber 43.
[0072] In this embodiment, the first chamber 42 is provided with a first pressure sensor 44 for collecting the hydraulic pressure in the first chamber 42, and the second chamber 43 is provided with a second pressure sensor 45 for collecting the hydraulic pressure in the second chamber 43, which can be used for subsequent specific control and adjustment.
[0073] In one embodiment, the first pressure sensor 44 is used to collect the hydraulic pressure of the first chamber 42, and the second pressure sensor 45 is used to collect the hydraulic pressure of the second chamber 43 to determine the hydraulic pressure difference on both sides of the hydraulic motor 31 and / or the hydraulic pressure difference on both sides of the piston 41.
[0074] In this embodiment, through the hydraulic pressure of the first chamber 42 collected by the first pressure sensor 44 and the hydraulic pressure of the second chamber 43 collected by the second pressure sensor 45, the hydraulic pressure difference on both sides of the hydraulic motor 31 and / or the hydraulic pressure difference on both sides of the piston 41 can be determined for subsequent specific control and adjustment.
[0075] In some embodiments, due to the connection of the fluid channels, the hydraulic pressure difference between the hydraulic pressure of the first chamber 42 and the hydraulic pressure of the second chamber 43 can be used as the hydraulic pressure difference on both sides of the hydraulic motor 31 and the hydraulic pressure difference on both sides of the piston 41, that is, the hydraulic pressure difference on both sides of the hydraulic motor 31 and the hydraulic pressure difference on both sides of the piston 41 can be the same.

The second end of the third pipeline section 3 communicates with the first cavity 42 and the second cavity 43 respectively.

The second end of the third pipeline section 3 communicates with the first cavity 42 and the second cavity 43 respectively. In this way, when the stabilizer bar 10 drives the piston 41 to move bidirectionally, the fluid can return to the first cavity 42 and the second cavity 43 through the third pipeline section 3, so that the hydraulic motor 31 can be driven to generate electricity.

[0102] This embodiment further provides a control method for a stabilizer bar power generation system. This method can be applied to any controller provided in the embodiments of the present application. Please refer to Figure 2 , the control method for the stabilizer bar power generation system provided in the embodiments of the present application includes: Step S10, regulating the opening regulating valve in the stabilizer bar power generation system according to vehicle information.
[0103] In this embodiment, the stabilizer bar power generation system can be disposed in a vehicle. The stabilizer bar in the stabilizer bar power generation system is connected to the suspension of the vehicle. By adjusting the damping of the stabilizer bar, the complex working conditions of the vehicle can be adapted, so as to better maintain the stability of the vehicle. For the damping control of the stabilizer bar, the flow needs to be restricted, and for the power generation control of the stabilizer bar, continuous fluid flow is required. Vehicle information of the vehicle where the stabilizer bar power generation system is located can be obtained. The vehicle information is relevant information involved in the running process of the vehicle, such as vehicle speed, steering wheel angle, lateral acceleration, road condition information of the road being traveled, etc. The vehicle information can characterize the working conditions of the vehicle, so as to judge the current demand for damping control or power generation control of the vehicle, and adjust the opening regulating valve in the stabilizer bar power generation system in combination with the vehicle information, so that the opening regulating valve in the stabilizer bar power generation system can be reasonably adjusted, adaptively restrict the flow of the fluid in the fluid pipeline, and coordinately adjust the damping of the stabilizer bar and the power generation power, so that the power generation efficiency of the stabilizer bar power generation system and the adjustment accuracy of the stabilizer bar damping are higher. Even under complex working conditions, the stabilizer bar power generation system can also produce good functional effects.
[0104] In one embodiment, the adjusting the opening regulating valve according to the vehicle information includes: Determining a target opening of the opening regulating valve according to the vehicle information; Adjusting the opening regulating valve according to the target opening.
[0105] In this embodiment, the required performance of the stabilizer bar of the vehicle can be judged according to the vehicle information. When the vehicle information characterizes that the vehicle is unstable, a lower target opening is selected to restrict the flow to increase the stabilizer bar damping to mainly maintain the vehicle stability. When the vehicle information characterizes that the vehicle is stable, a higher target opening can be selected to increase the flow to mainly generate power based on the stabilizer bar. In this way, determining the target opening regulating valve according to the vehicle information can more accurately realize the coordinated control of damping and power generation.
[0106] In one embodiment, the determining the target opening of the opening regulating valve according to the vehicle information includes: Determining control weight information between the damping control and the power generation control of the stabilizer bar power generation system according to the vehicle information; Determining the target opening of the opening regulating valve according to the control weight information.
[0107] In this embodiment, the vehicle information can characterize the working conditions of the vehicle, so as to determine the control weight information for the stabilizer bar power generation system on the vehicle to perform damping control and power generation control on the stabilizer bar. The control weight information can characterize the degree of currently needing to tend to damping control to improve vehicle stability or tend to power generation control to improve power generation efficiency, so as to determine the appropriate target opening of the opening regulating valve according to the control weight information for opening adjustment.
[0108] In one embodiment, the control weight information includes the damping weight coefficient corresponding to the damping control. Determining the target opening of the opening regulating valve according to the control weight information includes: Determining the target opening of the opening regulating valve according to the damping weight coefficient, the target damping torque of the damping control, and the hydraulic pressure difference between the two sides of the piston.
[0109] In this embodiment, the control weight information includes the damping weight coefficient corresponding to the damping control. The damping weight coefficient characterizes the degree of inclination towards damping control. The larger the damping weight coefficient, the greater the degree of damping control, and the larger the target opening should be. Furthermore, according to the damping weight coefficient, the target damping torque of the damping control, and the hydraulic pressure difference between the two sides of the piston, the target opening of the opening regulating valve is determined. The target damping torque of the damping control can be the maximum damping torque that can be achieved during damping control, which is the torque with the strongest damping effect. The hydraulic pressure difference between the two sides of the piston can be determined based on the hydraulic pressures collected by the first pressure sensor in the first cavity on the two sides of the piston and the second pressure sensor in the second cavity. The specific formula for calculating the target opening can be as follows:
[0110] Wherein, is the target opening, is the valve flow coefficient, is the hydraulic pressure difference between the two sides of the piston, is the target damping torque, is the damping weight coefficient.
[0111] Through the above formula, the target opening can be independently calculated by restricting according to the damping weight coefficient on the basis of the maximum opening for achieving the target damping torque, providing the adjustment accuracy and efficiency.
[0112] In some embodiments, on the basis of adjusting the opening regulating valve, the generator can also be synchronously adjusted to make it more adaptable to the flow rate change brought about by adjusting the opening regulating valve, so that the power generation efficiency of the generator is higher.
[0113] In one embodiment, the method further includes: Determining the target load of the generator in the stabilizer bar power generation system according to the control weight information; When adjusting the opening regulating valve according to the target opening, synchronously adjusting the generator according to the target load.
[0114] In this embodiment, the opening degree regulating valve and the generator can be adjusted synchronously. According to the control weight information, the target opening degree of the opening degree regulating valve in the stabilizer bar power generation system can be determined, and the target load of the generator in the stabilizer bar power generation system can also be determined. When the opening degree regulating valve is adjusted according to the target opening degree, the generator can be adjusted synchronously according to the target load. Since both are determined based on the control weight information, the coordination between the opening degree regulating valve and the generator can be improved, so that damping control and generator control can be carried out reasonably, and it can be applied to various complex working conditions of the vehicle.
[0115] In one embodiment, the control weight information includes the power generation weight coefficient corresponding to the power generation control. Determining the target load of the generator in the stabilizer bar power generation system according to the control weight information includes: Determining the target load of the generator according to the power generation weight coefficient, the target power generation power of the power generation control, and the power generation voltage of the generator.
[0116] In this embodiment, the control weight information includes the power generation weight coefficient corresponding to the power generation control. The power generation weight coefficient represents the degree of inclination towards power generation control. The larger the power generation weight coefficient, the greater the degree of power generation control, and the smaller the target opening degree should be. At the same time, in order to adapt to the reduced flow rate, the load of the generator can also be increased to match the hydraulic energy that the system can provide and improve the power generation efficiency. Furthermore, according to the power generation weight coefficient, the target power generation power of the power generation control, and the power generation voltage of the generator, the target load of the generator is determined. The target power generation power of the power generation control can be the maximum power generation power that can be achieved during power generation control, and the power generation voltage can be the rated voltage set for the generator. The formula for calculating the target load of the generator can be as follows:
[0117] where, R load is the target load, P gen is the target power generation power, V gen is the power generation voltage, and β is the power generation weight coefficient.
[0118] Through the above formula, the target load can be independently calculated by restricting according to the power generation weight coefficient on the basis of the load corresponding to the target power generation power, providing the adjustment accuracy and efficiency, realizing the coordinated control based on the target load and the target opening degree, further generating power while realizing the damping control, and reducing the energy loss.
[0119] In one example, the controller can output different currents to the opening regulating valve by outputting PWM signals (e.g., frequency 1 - 10 kHz, duty cycle 20% - 80%) to regulate the oil flow rate in the fluid pipeline. For example, a duty cycle of 50% corresponds to an opening of 50% of the opening regulating valve, allowing an oil flow rate of 25 L / min. The controller controls the converter of the generator and adjusts the load impedance of the generator according to the target load, e.g., 0.5 - 20 Ω, to match the current power generation requirement.
[0120] In this way, the opening regulating valve can receive currents corresponding to different duty cycles and execute the target opening of the corresponding opening regulating valve. Different openings correspond to different damping of the stabilizer bar to achieve the adjustment of the damping of the stabilizer bar. The generator converter receives the instructions from the controller and adjusts the load to match the power generation.
[0121] In one embodiment, determining the control weight information between the damping control and the power generation control of the stabilizer bar power generation system according to the vehicle information includes: Performing fuzzy calculation based on the vehicle information to determine the control weight information between the damping control and the power generation control of the stabilizer bar power generation system.
[0122] In this embodiment, fuzzy calculation can be performed based on the vehicle information to determine the control weight information between the damping control and the power generation control of the stabilizer bar power generation system under the current vehicle information, realizing dynamic decoupling, and dynamically determining the control weight information according to the vehicle information, thereby improving the accuracy of the coordinated regulation of power generation and damping.
[0123] In one embodiment, performing fuzzy calculation based on the vehicle information to determine the control weight information between the damping control and the power generation control of the stabilizer bar power generation system includes: For at least one piece of target vehicle information in the vehicle information, determining the matching degree between the target vehicle information and multiple fuzzy rules; According to the matching degree corresponding to each fuzzy rule and the reference weight information corresponding to each fuzzy rule, determining the control weight information.
[0124] In this embodiment, during the fuzzy calculation process, at least one piece of target vehicle information in the vehicle information can be used for fuzzy calculation. During the fuzzy calculation process, it is necessary to determine the matching degree between these target vehicle information and multiple fuzzy rules. Different fuzzy rules include reference weight information set according to different preset classification results of the vehicle information. Each fuzzy rule corresponds to a preset reference weight information to represent the degree to which the corresponding fuzzy rule favors power generation or damping control. By fusing the matching degree corresponding to each fuzzy rule and the reference weight information corresponding to each fuzzy rule, more refined control weight information can be determined.
[0125] In one embodiment, the reference weight information includes a reference damping weight coefficient and / or a reference power generation weight coefficient.
[0126] In this embodiment, the reference weight information corresponding to each fuzzy rule may include a reference damping weight coefficient and / or a reference power generation weight coefficient. These two parameters are the damping weight coefficient or the power generation weight coefficient preset for the fuzzy rule to characterize the degree of different fuzzy rules tending to power generation control or damping control.
[0127] In one embodiment, when the reference weight information includes a reference damping weight coefficient, determining the control weight information according to the matching degrees corresponding to the respective fuzzy rules and the reference weight information corresponding to the respective fuzzy rules includes: Performing a centroid calculation according to the matching degrees corresponding to the respective fuzzy rules and the reference damping weight coefficient in the reference weight information corresponding to the respective fuzzy rules to obtain a damping weight coefficient, so as to obtain the control weight information.
[0128] In this embodiment, the reference weight information may include a reference damping weight coefficient. A centroid calculation is performed according to the matching degrees corresponding to the respective fuzzy rules and the reference damping weight coefficient in the reference weight information corresponding to the respective fuzzy rules. The centroid calculation is the result obtained by comparing the weighted sum based on the matching degrees corresponding to the respective fuzzy rules and the reference damping weight coefficient in the reference weight information corresponding to the respective fuzzy rules with the sum of the reference damping weight coefficients in the reference weight information corresponding to the respective fuzzy rules, realizing the defuzzification of the fuzzy rules, thereby obtaining an accurate and appropriate damping weight coefficient to obtain the control weight information. The control weight information may further include a power generation weight coefficient. The power generation weight coefficient can be determined by subtracting the damping weight coefficient after the centroid calculation from a preset unit value (usually 1), and can also be used as the control weight information to participate in the coordinated control.
[0129] In one embodiment, when the reference weight information includes a reference power generation weight coefficient, determining the control weight information according to the matching degrees corresponding to the respective fuzzy rules and the reference weight information corresponding to the respective fuzzy rules includes: Performing a centroid calculation according to the matching degrees corresponding to the respective fuzzy rules and the reference power generation weight coefficient in the reference weight information corresponding to the respective fuzzy rules to obtain a power generation weight coefficient, so as to obtain the control weight information.
[0130] In this embodiment, the reference weight information may include a reference power generation weight coefficient. According to the matching degrees corresponding to each fuzzy rule and the reference power generation weight coefficient in the reference weight information corresponding to each fuzzy rule, a centroid calculation is performed. The centroid calculation is based on the matching degrees corresponding to each fuzzy rule and the reference power generation weight coefficient in the reference weight information corresponding to each fuzzy rule. After performing a weighted sum, the result is obtained by comparing it with the sum of the reference power generation weight coefficients in the reference weight information corresponding to each fuzzy rule, realizing the defuzzification of the fuzzy rules, thereby obtaining an accurate and appropriate power generation weight coefficient to obtain control weight information. The control weight information may further include a damping weight coefficient. By subtracting the power generation weight coefficient after the centroid calculation from a preset unit value (usually 1), the damping weight coefficient can be determined, which can also be used as control weight information to participate in collaborative control.
[0131] In one embodiment, for at least one piece of target vehicle information in the vehicle information, determining the matching degrees between the target vehicle information and multiple fuzzy rules includes: For at least one piece of target vehicle information in the vehicle information, determining the membership degrees of the target vehicle information under corresponding multiple preset classification results; Based on the membership degrees of the target vehicle information under corresponding multiple preset classification results and the preset classification results configured in each of the fuzzy rules, determining the matching degrees between the target vehicle information and each of the fuzzy rules.
[0132] In this embodiment, first, at least one piece of target vehicle information in the vehicle information is fuzzified. Based on a predefined membership function, the membership degree of each piece of target vehicle information under corresponding multiple preset classification results can be determined. According to the membership degrees of various target vehicle information under corresponding multiple preset classification results and the preset classification results configured for different vehicle information in each fuzzy rule, synthesis is performed, thereby determining the matching degrees between these target vehicle information and each fuzzy rule.
[0133] In one example, the steps for determining the control weight information are as follows: Step 1: Realize the fuzzification of the input parameters through the membership function, that is, the fuzzification of the target vehicle information; The membership function is defined as (taking the vehicle speed V as an example): Low speed (0 - 40 km / h): triangular function, with a peak at 20 km / h; Medium speed (30 - 70 km / h): trapezoidal function, with a platform interval of 40 - 60 km / h; High speed (60 - 120 km / h): Gaussian function, with a mean of 90 km / h and a standard deviation of 15 km / h. The fuzzification process is that when V = 35 km / h, the membership degrees are: 0.8 for low speed, 0.2 for medium speed, and 0.0 for high speed.
[0134] Step 2: Fuzzy rule inference; Fuzzy rule base:
[0135] Step 3: Rule triggering and weight synthesis; When V = 35 km / h (low speed membership degree is 0.8, medium speed membership degree is 0.2), and the steering wheel angle θ = 8 (small angle membership degree is 0.9, medium angle membership degree is 0.1), fuzzy rules 1 and 3 are triggered. The calculation results of the matching degrees of fuzzy rules 1 and 3 are: Proportion of rule 1 = 0.8×0.9 = 0.72; Proportion of rule 3 = 0.2×0.1 = 0.02.
[0136] Step 4: Defuzzification output Calculate the accurate damping weight coefficient α and power generation weight coefficient β through the centroid:
[0137] β = 1 - α = 0.21 where u i is the matching degree of the i-th rule, and α i is the reference damping weight coefficient in the i-th rule.
[0138] Through the above fuzzy calculation, the accurate damping weight coefficient α and power generation weight coefficient β can be determined to determine the control weight information for coordinating the control of the opening regulating valve and the generator.
[0139] In one embodiment, the method further includes: When the vehicle information meets the first preset condition of the balance control mode, determine the control weight information between the damping control and power generation control of the stabilizer bar power generation system according to the vehicle information, and determine the target opening of the opening regulating valve according to the control weight information.
[0140] In this embodiment, the vehicle information can be information related to vehicle operation, including the operation information of the vehicle itself, the road condition information of the road traveled, etc. Evaluate the vehicle working conditions according to the vehicle information, so as to switch the control mode of the stabilizer bar power generation system, such as the high damping control mode, the high power generation control mode, and the balance control mode, etc. Among them, the high damping control mode is to fix the low valve opening and small generator load to ensure sufficient damping and small power generation. The high power generation control mode is to fix the high valve opening and large generator load to provide small damping and ensure sufficient power generation power. The balance control mode is a mode of distributing the power generation weight coefficient and damping weight coefficient according to the working conditions characterized by the vehicle information, and the weights can be distributed through fuzzy calculation, and the target opening Kv, or the target opening Kv and the target load Rload of the generator can be calculated in real time. To accurately adjust the opening regulating valve and the generator in the system in real time to achieve coordinated control.
[0141] In one example, as Figure 3 shown, in the balanced mode, the vehicle information collected in real time is used as a variable input, and the membership degree of each vehicle information under multiple corresponding preset classifications is calculated to fuzzify the input variable. The matching degree is calculated through the defined fuzzy rule base, and then defuzzification is performed through centroid calculation to determine the target opening degree Kv and the target load Rload, and the corresponding control signals are output to the opening regulating valve and the generator for adjustment.
[0142] In one embodiment, the first preset condition includes: the vehicle information does not satisfy the second preset condition of the high power generation control mode, and the vehicle information does not satisfy the third preset condition of the high damping control mode.
[0143] In this embodiment, when the vehicle information neither satisfies the second preset condition of the high power generation control mode nor satisfies the third preset condition of the high damping control mode of the vehicle information, the stabilizer bar power generation system can perform the balanced control mode, and determine the control weight information according to the real-time vehicle information to determine the target opening degree, or adjust the target opening degree and the target load to achieve the coordinated adjustment of power generation and damping.
[0144] In one embodiment, the vehicle information includes at least one of vehicle speed, steering wheel angle, and lateral acceleration. In some embodiments, the vehicle information may further include road condition information of the road on which the vehicle travels, etc.
[0145] In one embodiment, the second preset condition includes: the steering wheel angle is less than or equal to a preset angle, or the lateral acceleration is less than a first lateral acceleration. When the steering wheel angle is less than or equal to the preset angle, or the lateral acceleration is less than the first lateral acceleration, it indicates that the vehicle is traveling in a straight line and is in a relatively stable state. At this time, the damping requirement is low, and the stabilizer bar power generation system can perform the high power generation control mode to achieve high power generation and low damping operation, so as to improve the power generation efficiency of the system under the corresponding working conditions.
[0146] In one embodiment, the third preset condition includes: the vehicle speed is greater than a preset vehicle speed, or the lateral acceleration is greater than a second lateral acceleration. When the vehicle speed is greater than the preset vehicle speed, or the lateral acceleration is greater than the second lateral acceleration, it indicates that the vehicle is in an unstable state. The stabilizer bar power generation system can perform the high damping control mode to achieve low power generation and high damping operation, so as to improve the stability of the system and the vehicle where it is located under the corresponding working conditions and improve driving safety.
[0147] In one embodiment, the method further includes: When the vehicle information satisfies the second preset condition of the high power generation control mode, determining a first preset opening degree as the target opening degree; and / or, When the vehicle information meets the third preset condition of the high-damping control mode, determine the second preset opening as the target opening, where the first preset opening is greater than the second preset opening.
[0148] In this embodiment, when the vehicle information meets the second preset condition of the high-power generation control mode and high-power generation control mode is required, the first preset opening can be determined as the target opening. When the vehicle information meets the third preset condition of the high-damping control mode and high-damping control mode is required, the second preset opening can be determined as the target opening, where the first preset opening is greater than the second preset opening, so that the flow rate of the high-damping control mode is less than that of the high-power generation control mode, thereby achieving the corresponding damping or power generation.
[0149] In one embodiment, in the high-power generation control mode, the load of the generator is the first preset load, and in the high-damping control mode, the load of the generator is the second preset load, and the first preset load is greater than the second preset load.
[0150] In this embodiment, in the high-power generation control mode, the load adjusted for the load of the generator is the first preset load, while in the high-damping control mode, the load adjusted for the load of the generator is the first preset load, thereby improving the power generation efficiency in the high-power generation control mode and the high-damping control mode.
[0151] In one embodiment, after adjusting the opening regulating valve in the stabilizer bar power generation system according to the vehicle information, it further includes: Adjust the generator in the stabilizer bar power generation system according to the flow rate of the fluid pipeline in the stabilizer bar power generation system and the hydraulic difference between both sides of the hydraulic motor in the stabilizer bar power generation system.
[0152] In some embodiments, when determining the target opening according to the vehicle information, the target load of the generator can also be determined synchronously according to the control weight information determined based on the vehicle information, so as to realize the synchronous adjustment of the opening regulating valve and the generator, thereby improving the response efficiency.
[0153] In this embodiment, the target opening can be determined according to the vehicle information and adjusted according to the target opening. The hydraulic difference between both sides of the hydraulic motor in the stabilizer bar power generation system is determined in real time through the first pressure sensor in the first cavity and the second pressure sensor in the second cavity, and the flow rate of the fluid pipeline in the stabilizer bar power generation system is collected through the flow sensor in the fluid pipeline. These data can characterize the strength of the hydraulic energy, so that the generator can be adjusted accurately in real time to improve the power generation efficiency.
[0154] In one embodiment, adjusting the generator in the stabilizer bar power generation system according to the flow rate of the fluid pipeline in the stabilizer bar power generation system and the hydraulic pressure difference on both sides of the hydraulic motor in the stabilizer bar power generation system includes: Determining the available power generation according to the flow rate of the fluid pipeline and the hydraulic pressure difference on both sides of the hydraulic motor; Adjusting the generator according to the available power generation.
[0155] In this embodiment, according to the flow rate of the fluid pipeline, the hydraulic pressure difference on both sides of the hydraulic motor, and the following formula, the available power generation provided by the hydraulic pressure can be calculated in real time: Pgen' = η·Δp2·Q Wherein, Pgen' is the available power generation, η is the system comprehensive efficiency, the typical value is 0.75, Δp2 is the hydraulic pressure difference on both sides of the hydraulic motor, and Q is the flow rate of the fluid pipeline.
[0156] Then, adjust the generator according to the available power generation so that the generator can adapt to the fluid flow in the fluid pipeline and improve the power generation efficiency.
[0157] In one embodiment, adjusting the generator according to the available power generation includes: Determining the target load of the generator according to the available power generation and the power generation voltage of the generator; Adjusting the generator according to the target load.
[0158] In this embodiment, according to the available power generation, the power generation voltage of the generator, and the following calculation formula, the target load of the generator can be determined, so that the generator can be accurately adjusted according to the target load:
[0159] In one example, as Figure 4 shown, the control process of the stabilizer bar power generation system includes three major parts: Perception part: including the Inertial Measurement Unit (IMU), the oil fluid perception system in the stabilizer bar power generation system, the power domain, etc.
[0160] Among them, the IMU collects the linear acceleration and angular acceleration of the vehicle's XYZ three axes, communicates through the Serial Peripheral Interface (SPI), and sends the lateral acceleration to the controller. The oil sensing system obtains the flow rate Q and hydraulic pressure P through a turbine flowmeter, a pressure sensor, etc. The power domain sends the current vehicle speed and gear information, etc., to the controller through CAN communication. The controller reads the information of the CAN signal to obtain vehicle information such as vehicle speed, gear position, and steering wheel angle.
[0161] Decision-making part: The controller mainly includes an input signal processing module, a working condition judgment module, a dynamic decoupling module, and an output signal processing module.
[0162] Among them, the input signal processing module converts the input signals of various communication methods to determine the vehicle information and outputs it to the working condition judgment module and the dynamic decoupling module.
[0163] Among them, the working condition judgment module can be divided into three modes according to vehicle information such as vehicle speed, steering angle, and lateral acceleration: High power generation control mode (judgment condition: steering wheel angle = 0° or lateral acceleration < 0.2g): Control objective: Maximize the power generation power, and increase the opening degree Kv of the opening regulating valve to 80%.
[0164] High damping control mode (judgment condition: vehicle speed > 120 km / h or lateral acceleration > 0.5g): Control objective: Give priority to ensuring the damping accuracy, and limit the opening degree Kv of the opening regulating valve to 20%.
[0165] Balanced control mode: (judgment condition: does not meet the conditions of the high power generation control mode and the high power generation control mode): The damping weight coefficient α corresponding to the damping control and the damping weight coefficient β corresponding to the damping control are dynamically adjusted to ensure the balance of power generation and damping. Determine the target opening degree and target load according to α and β. The controller outputs a PWM signal (frequency 1 - 10 kHz, duty cycle 20% - 80%) to the opening regulating valve drive based on the target opening degree to output different currents to regulate the fluid flow rate. For example, a duty cycle of 50% corresponds to a solenoid valve opening degree of 50%, allowing an oil flow rate of 25 L / min. The controller adjusts the converter of the generator based on the target load to adjust the load impedance, such as 0.5 - 20 Ω, to match the current power generation power demand.
[0166] In one example, first, the sensing part transmits information such as a lateral acceleration of 0.1g, a vehicle speed of 60 km / h, a steering wheel angle of 50°, and a pressure difference of 0.6 MPa to the working condition judgment module. The working condition judgment module selects the high power generation mode through the judgment condition that the acceleration < 0.2g. At this time, the target opening is fixed at 80%, corresponding to a duty cycle of 80%. At this time, the allowable oil flow rate is 40 L / min, and the generated power can be calculated to be 320 W. The target load of the generator is calculated according to the formula to obtain a load impedance of 7.2 Ω. The two signals, namely the PWM signal corresponding to the duty cycle and the load impedance signal, are output to the corresponding opening regulating valve and the generator, so as to control the proportional valve to open 80% and maintain the generated power at 320 W.
